The Indonesian treponematoses control project

Yaws control in Indonesia is based on use of the trained polyclinic nurse and his assistant, the "djuru-patek"; the polyclinics existed before the control began and each serves one subdistrict with a population of about 30 000. The campaign is thus part of the established health services from the start and consolidation presents few difficulties of integration. Surveys and resurveys are held by calling together the village population for examination and later for treatment. The maximum dose (1.2 million units of PAM) is given to active cases only. At resurveys most active cases are found in those who had latent or incubating yaws when seen earlier.It is pointed out that prevalence ratios of active cases to seroreactors of 1: 3-4 are probably due to previous treatment having been given; in previously untreated areas, a ratio of 1: 2 is more usual.In the consolidation stage, surveillance is maintained in polyclinics, villages and schools and the fullest co-operation of the population is sought, as it is at all stages of the campaign.
